I've been cloth diapering constantly for a little over 2 years. Bleach (with my hard water) has become my best friend. I can't wash my diapers with out it. If I do I get major lake water smell. Water itself is rough on the elastic, but so is using the diaper every day by stretching it to get a snug fit on your baby. The one thing I was very careful to avoid was putting my covers, pockets, and AIO in the dryer. So much so that I knew that if I wanted to be sure they were not put in the dryer, I had to do it myself. Occasionally (in the beginning I was using only covers/pf) a cover would hide in the prefolds and get tossed in the dryer. I used those covers for a good year before moving on to pockets and AIO. Never did I have any problem with weak snaps or de-laminating.
I started using pockets before my last son was born, so for a little over a year. For a majority of that year I took special precaution to hang all my covers, pockets, and AIO. I never had one problem with the PUL or snaps; and I really prided myself in that. I thought, "Awesome! These really will last through 2 children easily as long as I keep hanging them to dry." Plus my pockets were being used full time between two little bums. So after one year, they were/are in great shape. Lately though, I've slacked on that gentle care idea for my pockets, AIO, and wetbags. Yep, you guessed it. I've been putting them all in the dryer every other day when I do my diaper laundry. I've been doing this for about at least a month now and I sorely regret it.

This is a wet bag I had received. I used it once, washed it and when I went to hang it to dry the lining was completely separated from the outer cloth. Now, something like this is a manufacturing defect because I received another wet bag from same company in a different print, but it is still fine. This particular batch of material just was not made properly.

Now, I'm sure there are lots of moms out there who say they put their covers in the dryer, but I'm not sure that they all do it on high heat for 60-70 minutes every other day like I had been.

Broken snaps can be fixed though. I am thinking of getting myself a snap pliers to at least fix the broken snaps. After all having two in diapers, and losing two of my night diapers is not something I'm okay with. A de-laminated diaper, unless it is a manufacturing defect and it is within the one year warranty (check with the manufacturer for warranty info) your diaper, cover, or wet bag will be replaced. If it is user error, you are out of luck.
This is definitely a lesson learned that I am not willing to repeat.
